There’s something to be said for a one-time payment that actually sticks. This bundle on StackSocial pairs Microsoft Office Professional 2021 with Windows 11 Pro for just $54.97 (down from nearly $419), and it’s the kind of deal that makes sense if you’re setting up a new PC or finally updating an old one. The Office license is for life—no subscription, no annual fees, and it covers all the essentials, including Word, Excel, PowerPoint, Outlook, OneNote, Publisher, Access, and the free version of Teams. Everything installs locally on one Windows PC, so there’s no hopping between browser tabs or worrying about renewing in 12 months.

The Windows 11 Pro license, also included, is the full upgrade, not just cosmetic tweaks but real functionality gains. It’s got advanced tools like BitLocker encryption, Hyper-V virtualization, and Windows Sandbox for anyone dealing with professional-level tasks or sensitive data. If you’re switching from Windows 10 Home, you’ll notice productivity bumps too: snap layouts, tabbed File Explorer, and Copilot baked into the OS. That last one is Microsoft’s AI helper that lives on your taskbar. You can press the Windows key + C to launch it and ask it to summarize web pages, open apps, or adjust settings—all with plain English.

There are a few caveats. Note that you’ll need at least 4GB of RAM and 64GB of storage to run it, plus TPM 2.0 and UEFI support, so older PCs may be out. You can only use Office on one PC, and the license is tied to that device, not your Microsoft account, so it doesn’t travel with you if you upgrade to a new computer later. The Windows 11 Pro key gives you a bit more flexibility (it can be activated on up to two devices). And while it’s not compatible with virtual machines or Parallels, the deal still offers solid value for most everyday or professional users looking to avoid recurring costs. Just be sure to activate it within 30 days of buying.

For the last three months or so, I’ve been learning to use (and love) a Bambu Labs A1 3D printer, a big, loud machine that sits on my desk and turns pictures on my computer screen into real-world objects.

In the first part of my series about diving into the wild world of 3D printers, I covered what I’d learned about the different types of 3D printers, some useful settings in the Bambu Studio app (which should also be broadly useful to know about no matter what printer you use), and some initial, magical-feeling successes in downloading files that I turned into useful physical items using a few feet of plastic filament and a couple hours of time.

For this second part, I’m focusing on what I learned when I embarked on my first major project—printing upgrade parts for the A1 with the A1. It was here that I made some of my first big 3D printing mistakes, mistakes that prompted me to read up on the different kinds of 3D printer filament, what each type of filament is good for, and which types the A1 is (and is not) good at handling as an un-enclosed, bed-slinging printer.

Steven J. Vaughan-Nichols writes in an op-ed for The Register: I use AI a lot, but not to write stories. I use AI for search. When it comes to search, AI, especially Perplexity, is simply better than Google. Ordinary search has gone to the dogs. Maybe as Google goes gaga for AI, its search engine will get better again, but I doubt it. In just the last few months, I’ve noticed that AI-enabled search, too, has been getting crappier.

In particular, I’m finding that when I search for hard data such as market-share statistics or other business numbers, the results often come from bad sources. Instead of stats from 10-Ks, the US Securities and Exchange Commission’s (SEC) mandated annual business financial reports for public companies, I get numbers from sites purporting to be summaries of business reports. These bear some resemblance to reality, but they’re never quite right. If I specify I want only 10-K results, it works. If I just ask for financial results, the answers get… interesting. This isn’t just Perplexity. I’ve done the exact same searches on all the major AI search bots, and they all give me “questionable” results.

Welcome to Garbage In/Garbage Out (GIGO). Formally, in AI circles, this is known as AI model collapse. In an AI model collapse, AI systems, which are trained on their own outputs, gradually lose accuracy, diversity, and reliability. This occurs because errors compound across successive model generations, leading to distorted data distributions and “irreversible defects” in performance. The final result? A Nature 2024 paper stated, “The model becomes poisoned with its own projection of reality.” […]

We’re going to invest more and more in AI, right up to the point that model collapse hits hard and AI answers are so bad even a brain-dead CEO can’t ignore it. How long will it take? I think it’s already happening, but so far, I seem to be the only one calling it. Still, if we believe OpenAI’s leader and cheerleader, Sam Altman, who tweeted in February 2024 that “OpenAI now generates about 100 billion words per day,” and we presume many of those words end up online, it won’t take long.

SpaceX made some progress on another test flight of the world’s most powerful rocket Tuesday, finally overcoming technical problems that plagued the program’s two previous launches.

But minutes into the mission, SpaceX’s Starship lost control as it cruised through space, then tumbled back into the atmosphere somewhere over the Indian Ocean nearly an hour after taking off from Starbase, Texas, the company’s privately-owned spaceport near the US-Mexico border.

SpaceX’s next-generation rocket is designed to eventually ferry cargo and private and government crews between the Earth, the Moon, and Mars. The rocket is complex and gargantuan, wider and longer than a Boeing 747 jumbo jet, and after nearly two years of steady progress since its first test flight in 2023, this has been a year of setbacks for Starship.

An anonymous reader quotes a report from Axios: Advanced robots don’t necessarily need to look like C3PO from “Star Wars” or George Jetson’s maid Rosie, despite all the hype over humanoids from Wall Street and Big Tech. In fact, some of the biggest skeptics about human-shaped robots come from within the robotics industry itself. […] The most productive — and profitable — bots are the ones that can do single tasks cheaply and efficiently. “If you look at where robots are really bringing value in a manufacturing environment, it is combining industrial or collaborative robots with mobility,” ABB managing director Ali Raja tells Axios. “I don’t see that there are any real practical applications where humanoids are bringing in a lot of value.”

“The reason we have two legs is because whether Darwin or God or whoever made us, we have to figure out how to traverse an infinite number of things,” like climbing a mountain or riding a bike, explains Michael Cicco, CEO of Fanuc America Corp. “When you get into the factory, even if it’s a million things, it’s still a finite number of things that you need to do.” Human-shaped robots are over-engineered solutions to most factory chores that could be better solved by putting a robot arm on a wheeled base, he said.

“The thing about humanoids is not that it’s a human factor. It’s that it’s more dynamically stable,” counters Melonee Wise, chief product officer at Agility Robotics, which is developing a humanoid robot called Digit. When humans grab something heavy, they can shift their weight for better balance. The same is true for a humanoid, she said. Using a robotic arm on a mobile base to pick up something heavy, “it’s like I’m a little teapot and you become very unstable,” she said, bending at the waist.

SpaceX’s Starship Flight 9 successfully launched and reached space — marking the first reuse of a Super Heavy booster — but both rocket stages were ultimately lost mid-mission due to a “rapid unscheduled disassembly.” SpaceX CEO Elon Musk said in a statement: “Starship made it to the scheduled ship engine cutoff, so big improvement over last flight! Leaks caused loss of main tank pressure during the coast and re-entry phase. Lot of good data to review.” Musk said the next three Starship test launches could lift off every three to four weeks in the days ahead. Space.com reports: The mission lifted off from Starbase today at 7:37 p.m. EDT (2337 GMT; 6:37 p.m. local Texas time), sending the 40-story-tall rocket into the Texas sky atop a pillar of flame. It was a milestone launch, marking the first-ever reuse of a Super Heavy booster; this one earned its wings on Flight 7 in January. (SpaceX swapped out just four of its Raptors after that mission, meaning that 29 of the engines that flew today were flight-proven.) “Lessons learned from the first booster refurbishment and subsequent performance in flight will enable faster turnarounds of future reflights as progress is made towards vehicles requiring no hands-on maintenance between launches,” the company wrote in a Flight 9 mission preview.

The Super Heavy had a somewhat different job to do today; it conducted a variety of experiments on its way back down to Earth. For example, the booster performed a controlled rather than randomized return flip and hit the atmosphere at a different angle. “By increasing the amount of atmospheric drag on the vehicle, a higher angle of attack can result in a lower descent speed, which in turn requires less propellant for the initial landing burn,” SpaceX wrote in the mission preview. “Getting real-world data on how the booster is able to control its flight at this higher angle of attack will contribute to improved performance on future vehicles, including the next generation of Super Heavy.” These experiments complicated Super Heavy’s flight profile compared to previous missions, making another “chopsticks” catch at Starbase a tougher proposition. So, rather than risk damaging the launch tower and other infrastructure, SpaceX decided to bring the booster back for a “hard splashdown” in the Gulf of Mexico on Flight 9. That was the plan, anyway; Super Heavy didn’t quite make it that far. The booster broke apart about 6 minutes and 20 seconds into today’s flight, just after beginning its landing burn. “Confirmation that the booster did demise,” [Dan Huot, of SpaceX’s communications team] said during the Flight 9 webcast. Super Heavy’s flight ended “before it was able to get through landing burn,” he added.

Ship, by contrast, improved its performance a bit this time around. It reached space today on a suborbital trajectory that took it eastward over the Atlantic Ocean — the same basic path the vehicle took on the truncated Flight 7 and Flight 8. But Flight 9 got choppy for Ship after that. The vehicle was supposed to deploy eight dummy versions of SpaceX’s Starlink satellites about 18.5 minutes after liftoff, which would have been a landmark first for the Starship program. That didn’t happen, however; the payload door couldn’t open fully, so SpaceX abandoned the deployment try. Then, about 30 minutes after launch, Ship started to tumble, which was the result of a leak in Ship’s fuel-tank systems, according to Huot. “A lot of those [tanks] are used for your attitude control,” he said. “And so, at this point, we’ve essentially lost our attitude control with Starship.” As a result, SpaceX nixed a plan to relight one of Ship’s Raptor engines in space, a test that was supposed to happen about 38 minutes after launch. And the company gave up hope of a soft splashdown for the vehicle, instead becoming resigned to a breakup over the Indian Ocean during Ship’s reentry.

The company therefore will not get all the data it wanted about Flight 9. And there was quite a bit to get; for example, SpaceX removed some of Ship’s heat-shield tiles to stress-test vulnerable areas, and it also tried out several different tile materials, including one with an active cooling system. But the company plans to bounce back and try again soon, just as it did after Flight 7 and Flight 8. You can watch a recording of the launch on YouTube.

unixbhaskar shares a report from Phoronix: The X86_NATIVE_CPU Kconfig build time option has been merged for the Linux 6.16 merge window as an easy means of enforcing “-march=native” compiler behavior on AMD and Intel processors to optimize your kernel build for the local CPU architecture/family of your system. For those wanting to “-march=native” your Linux kernel build on AMD/Intel x86_64 processors, the new CONFIG_X86_NATIVE_CPU option can be easily enabled for setting that compiler option on your local kernel builds.

The CONFIG_X86_NATIVE_CPU option is honored if compiling the Linux x86_64 kernel with GCC or LLVM Clang when using Clang 19 or newer due to a compiler bug with the Linux kernel on older compiler versions. In addition to setting the “-march=native” compiler option for the Linux kernel C code, enabling this new Kconfig build option also sets “-Ctarget-cpu=native” for the kernel’s Rust code too.

“It seems interesting though,” comments unixbhaskar. “If the detailed benchmark shows some improvement with the option selected, then distros might start to adopt it for their flavor.”

Cloudflare CEO Matthew Prince warned that LaLiga’s ISP blocking campaign — intended to stop football piracy — has caused widespread collateral damage by blocking millions of unrelated websites, including emergency services, in Spain. He called the strategy “bonkers” and expressed fear that lives could be lost due to the overblocking. TorrentFreak reports: Posting to X last week, Prince asked if anyone wanted any general feedback, declaring that he felt “in an especially truthful mood.” The first response contained direct questions about the LaLiga controversy, the blame for which LaLiga places squarely on the shoulders of Cloudflare. For the first time since Cloudflare legal action failed to end LaLiga’s blocking campaign, Prince weighed in with his assessment of the current situation and where he believes it’s inevitably heading.

“A huge percentage of the Internet sits behind us, including small businesses and emergency resources in Spain,” Prince explained. “The strategy of blocking broadly through ISPs based on IPs is bonkers because so much content, including emergency services content, can be behind any IP. The collateral damage is vast and is hurting Spanish citizens from accessing critical resources,” he added. […]

Despite LaLiga’s unshakable claims to the contrary, Prince believes that it’s not a case of ‘if’ disaster strikes, it’s ‘when.’ “It’s only a matter of time before a Spanish citizen can’t access a life-saving emergency resource because the rights holder in a football match refuses to send a limited request to block one resource versus a broad request to block a whole swath of the Internet,” Prince warned. “When that unfortunately and inevitably happens and harms lives, I’m confident policy makers and courts in Spain and elsewhere will make the right policy decision. Until then, it’ll be up to users to make politicians clear on the risk. I pray no one dies.”

The suggestion that LaLiga’s demands were too broad, doesn’t mean that Cloudflare is refusing to help, Prince suggested. On the contrary, there’s a process available, LaLiga just needs to use it. “We’ve always been happy and willing to work with rights holders in conjunction with judicial bodies to protect their content. We have a clear process that works around the world to do that,” Prince explained.

If you’ve been eyeing a lightweight, all-purpose Chromebook for casual work, school, or everyday browsing, this open-box ASUS Chromebook CM30 might be worth a closer look. Currently priced at $179.99 (down from $329.99), it’s one of those mid-range 2-in-1s that doesn’t try to be everything, but nails the basics with enough flair to feel premium. The 10.5-inch WUXGA touchscreen is responsive and sharp, and thanks to the Kompanio 520 processor and 8GB of RAM, general multitasking is smooth, whether you’re juggling docs, Google Meet, or your Spotify tab. ChromeOS keeps things lean and fast, and you also get stylus support for quick notes or digital doodles.

It helps that the whole device is wrapped in a sturdy aluminum shell (made with 30% recycled materials), giving it that slightly rugged, school-bag-ready feel without adding bulk. The detachable magnetic keyboard is full-sized and easy to type on, and the included stand cover lets you switch between laptop and tablet mode without a fuss. The battery claims up to 12 hours of life, and while real-world usage may land a bit under that, you’ll still comfortably get through a school or work day without hunting for an outlet (which is really all you can ask from a sub-two-pound machine). Wi-Fi 6 and Bluetooth 5.3 keep connectivity solid, and the Titan C security chip adds a layer of peace of mind.

The Chromebook is an “Open Box” model, meaning that the units aren’t brand new—they’re returns or unsold inventory that may show minor signs of handling. You may find stickers or shelf wear on the packaging, but the product itself should be clean and fully functional, with a one-year warranty included. If you’re looking for a 2-in-1 Chromebook that’s not underpowered like budget models but still doesn’t stretch your wallet, this deal should hit that balance. That said, the 128GB eMMC storage isn’t expandable, and there’s only one USB-C port, so those who need lots of peripherals or file space might want to look elsewhere. For everyone else, especially students or remote workers, it’s a solid, sustainable pick.
